Hi All

Hopefully collecting my new car on Monday. It’s a 2017 S 350d with the 20 inch AMG alloys. I want to replace all of the Wheel nuts. Can someone confirm please the exact size of the lug nuts I’m getting lots of conflicting info when searching online. Thanks.

There are three specs for the lug bolt (not nut, at least on USA-spec cars):

Seat type (USA cars have rounded or ball seats);
Shank length (our 20" AMG alloy wheels take a 45MM shank), and
Thread pitch (pretty sure 1.5mm)

Diesel Benz

Also 14 mm bolts, Mercedes used to have 12 mm bolts too on older models. All OEM are with rounded seat as above, after market wheels often different.

Don't think they would use left hand threads if that is what you were wondering.

I did not check the bolt length but everything above should apply in Ireland too.

EDIT: EPC says M14 x 1,5 x 48,5
